Featuring high current capacity (up to 100kA impulse current) and low residual voltage, M-LBS 5000 adopts pluggable lightning protection modules for easy maintenance and replacement.
The built-in lightning status monitoring (counting) system accurately records lightning strikes, while the sound and light alarm function provides real-time alerts for SPD failures.
M-LBS 5000 is a high-performance three-phase AC power lightning protection box designed for LPZ 0B-1 and subsequent partitions.
It is specifically installed in equipment-intensive rooms such as communication base stations, broadcasting and television system rooms, computer rooms,
and medical equipment rooms to provide comprehensive lightning protection for three-phase AC distribution systems.

Notices
●Install the lightning protection box in a well-ventilated, dry indoor environment away from flammable and explosive materials.
●Use wiring with cross-sectional area 6mm²-32mm² and tighten screws to 5N·m torque.
●Ensure the grounding system meets requirements (ground resistance ≤4Ω) for optimal surge diversion.
●Regularly check the lightning strike count and status indicator—replace faulty modules immediately.
●The product is heavy; ensure the installation surface can bear its weight (product size: 510mmx370mmx140mm).
●Only qualified electricians are allowed to install, maintain, or replace modules to avoid electrical hazards.
